How to convert Japanese text to speech

  1. Write or paste your Japanese text into the box. A sentence, a script, or a full article all work.
  2. Open Settings and set the language to Japanese. This page opens with Japanese already selected, so you only need to check it.
  3. Pick a voice from the chips, or open More voices to hear the full lineup of 28. Every voice can read Japanese.
  4. Press Generate speech and the audio plays right away, then press Download MP3 to save the file to your device.

That is the whole flow. Without an account: 20 uses a day, up to 1,000 characters each.

How to write Japanese text that sounds natural

  • Punctuation sets the pacing. A comma 、 marks the short break inside a sentence and a period 。 closes one, so normal sentence punctuation gives the read a place to breathe. A long line with no punctuation comes back as one breathless take.
  • A kanji word can have more than one reading, and names and rare words are where the read is most likely to surprise you. If a word must be read one specific way, spell it in kana instead of kanji.
  • Numbers and English abbreviations can be read in more than one way. Listen to a short sample first, and if the reading is not the one you wanted, write the number or abbreviation out the way it should be spoken.
  • Every voice reads the same words a little differently, so audition two or three voices with a short paragraph before you commit a long script.

This page is one preset of the site's main text to speech tool: the same 28 voices and 20 languages, with the language selector free to change. If your text is in another language, start there.
